摘要： PURPOSE: To prevent settlement due to the consolidation of a sea-bottom ground by laminating and laying and arranging a large number of blocks in a specified sea area under an approximately floated state while surrounding the peripheries of the blocks by coffering walls. CONSTITUTION: A large number of steel-pipe sheet piles 1 are driven continuously while surrounding the periphery of the constructed sea area S of an artificial island 20, thus installing a coffering wall 10. Sand drains 5 are driven into an alluvial clay layer 21 in the coffering wall 10 to compact the ground while paving sand 6 is laid on a floor-face ground 22, and a temporary bearing base 7 is mounted. Box culverts 2 are sunk successively into the coffering wall 10, and the culverts 2 are arranged closely under an approximately floated state. Sections among the culverts 2 in a lower layer and paving sand 6 are filled with mortar, the upper sections of the culverts 2 are filled up with lightweight aggregate 9, and a top face is paved 25. Accordingly, the loading of placing load in size, by which settlement due to consolidation is generated on a sea- bottom ground, can be prevented, and the artificial island 20 can be executed easily.

摘要： PURPOSE: To obtain a stable ground simply and rapidly even when the large- scale ground must be prepared. CONSTITUTION: An artificial island 30 is composed of a coffering wall 40 formed by driving and installation to the periphery of a sea area S while surrounding the sea area S, in which the artificial island 30 must be built, up to the depth reaching an impermeable layer 20 in the lower section of a sea-bottom ground 22 from a marine section, box culverts 2 as a large number of blocks closely arranged crosswise under a floated state in the sea area S surrounded by the coffering wall 40, and waste products 10 charged and filled into a space section 4 in the lower section of the box culverts 2. The artificial island 30 is constructed in such a manner that the coffering wall 40 is driven and mounted, the separately manufactured box culverts 2 are disposed closely on the inside of the coffering wall 40, and the waste products 10 are charged and filled into the space section 4 while utilizing the top faces of the box culverts 2 as a ground surface.

摘要： PROBLEM TO BE SOLVED: To provide a caisson structural body capable of preventing a member strength from being excessively designed by eliminating nonuniformity of reinforcement arrangement to save labor and provide a wave power dissipation function. SOLUTION: A structural body 10 comprises a reinforced concrete side wall part 12 and a bottom board part 14. The side wall part 12 has a horizontal cross-section formed in cylindrical shape, its interior is made hollow, and its bottom end side is closed so as to form it integrally with the bottom board part 14. On the outer periphery of the side wall part 12, a fitted recessed part 18 forming one of connection parts 16 is formed at specified intervals in circumferential direction. A component member on the other side of the connection part 16 is a curved plate 20, and both end sides of the curved plate 20 are inserted between the fitted recessed parts 18 of the side wall parts 12 adjacent to each other when a plurality of caisson structural bodies 10 are sunk so as to be adjacent to each other on a water bottom ground.
